linux  hadoop-ha  三台机器 安装

 

0.规定

 

IP                   hostname                 role
10.156.50.35       master1                  主节点
10.156.50.36       master2                  备份主节点
10.156.50.37       slaver1                  从节点

 

 

1. 创建 zkkafka 用户

 

useradd zkkafka
passwd zkkafka

zkkafka

 

 

2.修改 sudoers

 

chmod -R 777 /etc/sudoers

## Allow root to run any commands anywhere 
root	ALL=(ALL) 	ALL
zkkafka ALL=(ALL)       ALL
## Allows members of the 'sys' group to run networking, software, 
## service management apps and more.
# %sys ALL = NETWORKING, SOFTWARE, SERVICES, STORAGE, DELEGATING, PROCESSES, LOCATE, DRIVERS

## Allows people in group wheel to run all commands
%wheel	ALL=(ALL)	ALL
%wheel  ALL=(ALL)       NOPASSWD: ALL
## Same thing without a password


chmod -R 440 /etc/sudoers

sudo scp /etc/sudoers root@10.156.50.36:/etc/
sudo scp /etc/sudoers root@10.156.50.37:/etc/

 

 

3.修改 hosts

 

[zkkafka@yanfabu2-35 ~]$ sudo cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

10.156.50.35 yanfabu2-35.base.app.dev.yf zk1  hadoop1 master1  master
10.156.50.36 yanfabu2-36.base.app.dev.yf zk2  hadoop2 master2
10.156.50.37 yanfabu2-37.base.app.dev.yf zk3  hadoop3 slaver1


sudo scp /etc/hosts root@10.156.50.36:/etc/
sudo scp /etc/hosts root@10.156.50.37:/etc/

 

 

4.修改主机交换空间 集群的selinux 

 

vim /etc/sysctl.conf  
        vm.swappiness = 0 

 setenforce 0  
    vi /etc/selinux/config  
        SELINUX=disabled 

sudo scp /etc/sysctl.conf root@10.156.50.36:/etc/
sudo scp /etc/sysctl.conf root@10.156.50.37:/etc/

 

 

5.关闭防火强

 

service iptables status  
service iptables stop 

 

 

6.生成免密登陆 第一次ssh需要密码

 

master   slave
    ssh-keygen -t rsa 空格 空格  
    cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys  

slave 
    ssh-copy-id -i hadoop1
    ssh-copy-id -i hadoop1

master
    chmod 600 authorized_keys
    scp ~/.ssh/authorized_keys zkkafka@10.156.50.36:~/.ssh/  
    scp ~/.ssh/authorized_keys zkkafka@10.156.50.37:~/.ssh/ 

 

 

7.安装hadoop

 

7.1 解压tar xf hadoop-2.6.5.tar.gz

7.2 重命名mv hadoop-2.6.5 hadoop

7.3 创建文件夹mkdir -p tmp hdfs hdfs/datanode hdfs/namenode hdfs/logs hdfs/journal

 

/home/zkkafka/hadoop/tmp
/home/zkkafka/hadoop/hdfs
/home/zkkafka/hadoop/hdfs/datanode
/home/zkkafka/hadoop/hdfs/namenode
/home/zkkafka/hadoop/hdfs/logs
/home/zkkafka/hadoop/hdfs/journal

 

 

7.4 修改环境变量

 

vi ~/.bash_profile

export HADOOP_HOME=/home/zkkafka/hadoop
export PATH=$JAVA_HOME/bin:$HADOOP_HOME/bin:$PATH

source ~/.bash_profile

 

 

 

7.5 需要修改文件

 

/home/zkkafka/hadoop/etc/hadoop/hadoop-env.sh
/home/zkkafka/hadoop/etc/hadoop/yarn-env.sh
/home/zkkafka/hadoop/etc/hadoop/core-site.xml
/home/zkkafka/hadoop/etc/hadoop/hdfs-site.xml
/home/zkkafka/hadoop/etc/hadoop/mapred-site.xml
/home/zkkafka/hadoop/etc/hadoop/yarn-site.xml
